Reason: In birds, male heterogamety is seen as males produce two different types of gametes. AIf both assertion and reasons are true and the reason is the correct explanation of the assertion. BIf both assertion and reason are true but reason is not the correct explanation of the assertion...
In males, this phase is referred to as the spermatogonial phase during which spermatogonial cells are produced. In females of most vertebrates, the gonial phase occurs very early in the life cycle and establishes a population of oogonia within the ovary. During the subsequent gametogenic phase ...
Describe the difference in the production of sperm by males and eggs by females. What is the process of forming organs called? Give two examples in each case of organs or tissues in which you would expect (a) meiosis, (b) mitosis to be taking place. ...
The term "gametes" is another way of describing sex cells within organisms. Both males and females that reproduce sexually must produce gametes in order to conceive offspring. Answer and Explanation:1 In humans, the male gamete which is sperm is produced within the testes while the female gamet...

Here we studied a population of fowl, Gallus gallus, to gain longitudinal data on a sexual ornament (the comb), quantity of gametes produced, and gamete quality (sperm velocity and egg mass) of males and females. Our results reveal pronounced differences between the sexes in age-specific ...
(AT) hybrid was obtained from cross- ing red crucian carp (RCC; C. auratus red var., ♀, 2n = 100) with common carp (CC; Cyprinus carpio L., ♂, 2n = 100)21,22, in which both the females and males are fertile, producing diploid eggs and diploid ...
Directly editing gametes could overcome mosaicism, but this is hindered in males by the makeup of the sperm cells, and in females by the low technical efficiency and the low number of mature oocytes collected per patient. CRISPR ... S Segers 被引量: 0发表: 2017年 In vitro gametogenesis, ...

What are the basic properties of gametogenesis in males and in females? During which process are gametes (sperm and egg) produced? (a) Mitosis (b) Budding (c) Binary Fission (d) Meiosis. Explain how meiosis and sexual reproduction ...
